Abstract (en)
[origin: WO2020176032A2] A wireless device (16) suspends a connection (18) with a first access network (12A) and enters an inactive state. While the connection (18) with the first access network (12A) is suspended and the wireless device (16) is in the inactive state, the wireless device (16) camps in a specific area (24B) of a second wireless communication network (10B) that is included in a notification area (24) within which the wireless device (16) is allowed to move without notifying either the second wireless communication network (10B) or a first wireless communication network (10A) that includes the first access network (12A). Upon camping in the specific area (24B), the wireless device (16) starts a timer (40). Responsive to expiry of the timer (40), the wireless device (16) switches from the inactive state to an idle state and/or transmits to the second access network (12B) signaling (26) indicating that the wireless device (16) is in the specific area (24B) or that the wireless device (16) requests a connection to the second access network (12B).
